THE BEHAVIOR OF MAJOR ROCK-FORMING MINERALS AND VOLATILES DURING THE GIANT IMPACT
PhD or postdoctoral openings – starting September 2018
Two openings at the level of PhD or postdoctoral are available for the IMPACT ERC project based in Lyon, France, starting with September 1st, 2018. IMPACT aims to retrace the thermodynamic path of the condensation of the protolunar disk, to bring physical and chemical constraints on the impact model, and to characterize the formation of the Moon and of the Earth.
The position is to study the behavior of major rock-forming minerals during the Giant Impact. Immediately after the impact, the largest parts of both the proto-Earth and the impactor melted and vaporized. They accumulated into a large protolunar disk. Everything inside the Roche radius fell down and condensed to form the early Earth. The outer parts partly fell onto the Earth, partly condensed to form the moon and partly were lost to space.
The aim of the doctoral work is to determine the physical properties and the chemical behavior of the corresponding mineral melts at conditions characteristic to the Giant Impact. For this, the successful candidate(s) will use ab initio molecular-dynamics simulations. He/she will compute the equations of state of the liquid, gas and supercritical states, position the supercritical points and/or surfaces, determine the chemical speciation in the fluids, and predict isotope partitioning factors.
